This study confirms the effectiveness of aerobic exercise on waist circumference, Vo2 max, blood glucose, insulin, serum lipid in middle-aged women. The Ovid-Medline, Embase, the Cochrane Library, and CINAHL were searched. The risk of bias 2 revised in 2019 was used to assess the risk of bias in randomized controlled trials (RCTs). Selected studies were meta-analyzed with Review Manager 5.3. Data were compiled from 15 RCTs comprising 1,110 participants. Overall, aerobic exercise reduced waist circumference and blood glucose, and increased VO2 max significantly. We recommend the application of aerobic exercise to prevent metabolic disease in middle-aged women.High viability and further adipogenic differentiation of adipose-derived stem cells (ADSCs) are fundamental for engraftment and growth of the transplanted adipose tissue. It has been demonstrated that extracellular matrix (ECM) regulates cell proliferation and differentiation by interacting with ERK1/2 signalling pathway. In this study, we prepared autologous decellularized extracellular matrix (d-ECM) and explored its effect on the proliferation and adipogenic ability of ADSCs in low serum culture. We found that 2% foetal bovine serum (FBS) in growth medium inhibited cell viability and DNA replication, and decreased mRNA and protein levels of PPARγ and C/EPBα compared with 10% FBS. Correspondingly, after 14-days adipogenic induction, cells cultured in 2% FBS possessed lower efficiency of adipogenesis and expressed less adipocyte differentiation markers ADIPOQ and aP2. On the contrary, the d-ECM-coated substrate continuously promoted the expression of PPARγ, and regulated the phosphorylation of ERK1/2 in different manners during differentiation. Pretreatment with ERK1/2 inhibitor PD98059 neutralized the effects of d-ECM, which suggested d-ECM might regulate the adipogenesis of ADSCs through ERK1/2-PPARγ pathway. In addition, d-ECM was revealed to regulate the transcription and expression of stemness-associated genes, such as OCT4, NANOG and SOX2, in the undifferentiated ADSCs, which might be related to the initiation of differentiation.The purpose of this short review is to give a personal appreciation of a woman who was my mentor and friend and who made enormous contributions in the field of translational radiation biology.
Julie Denekamp was a talented and charismatic scientist and teacher. She was a major contributor to our understanding of the effects of fractionation schedules on the response of tumors and normal tissues to radiotherapy and of factors that could be manipulated to alter these responses. She was also one of the first to recognize that the fragile state of tumor vasculature could be exploited in targeted radiotherapy.

We aimed to ascertain if there was any difference in perioperative morbidities between these two approaches.
We performed a retrospective review of laparoscopic TP and RP nephrectomies performed in our institution over 10?years from May 2009 till May 2019. Outcome measures included intraoperative complications, prolonged requirement of opioid analgesics (more than 24?h), hospital stay, incidence of wound infection and urinary tract infections. Data were analysed using Fisher's exact test and Mann Whitney test.
A total of 152 nephrectomies were performed in 139 patients; 81 were TP and 71 were RP. Age ranged from 8?months to 16?years. Median hospital stay was 2?days in both groups. There were no intraoperative complications. Outcome measures were sub-categorised as follows. Requirement of opioid analgesia for more than 24?h was documented in 2 patients in each group, leading to longer hospital stay of 3?days. A febrile urinary tract infection requiring antibiotics was detected in 4; 1 in TP and 3 in RP. Wound infection requiring antibiotics occurred in 1 patient (in RP group). No statistically significant difference was found between the two groups in any of the subcategories.
TP and RP nephrectomy have similar perioperative morbidity. The decision to utilise either approach should be dependent on the surgeon's skills and experience and appropriately tailored to individual patient needs.

A successful match into an ophthalmology residency was achieved by 144 (83.7%) applicants. Applicants applied to (mean ± SD) 79.7 ± 22.8 ophthalmology residency pr the COVID-19 pandemic. Although many applicants and PDs were glad that interviews were held virtually this year, they were less certain regarding future years. The virtual format led to a significantly lower financial burden for applicants and may lead some to prefer this format in the future; if a hybrid model is offered for virtual/in-person interviews, these two interview modes should be compared equally.
